STACKER.

- Specification of Letters Patent.

Application filed June 22, 1906.

Patented April 14, 1908.

Serial No. 322,868.

To all whom it may concern:

Be it known that I, HIRAM W. BLAISDELL,

a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Stackers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hydro-metallurgical apparatus and more articularly to mechanism designed for distriiiuting or stacking the spent residue or tailings of hydrometallurglcal processes.

It is an object of this invention to provide an apparatus of this class that may be used upon a removable track and that will automatically run backward and forward on said track throwing thematerial to either side.

It is also an object of this invention to provide an apparatus of this sort wherein the power use for progressing the apparatus and for distributing the material, is derived independently of the conveyor which delivers the material to said apparatus.

Another object of the invention is to provide an a paratus of this character wherein the distrihuting device may be operated to discharge the material in any desired direction.

A further object of the invention is to pro vide an apparatus that can be used to throw the material in advance of itself until the pile of material is of suflicient height, whereupon tracks may be laid on top of it and the apparatus operated as at first described.

With these, and other objects in view, this invention consists essentially in the construction and combination of parts herein described and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the apparatus; Fig. 2 is a plan of the forward portion of the same; Fig. 3 is a perspective detail of a portion of the reversing mechanism; Fig. 4 is an elevation of a portion of the rear of the apparatus, taken from the opposite side to Fig. 1; Fig. 5 is a diagrammatic view of the apparatus working upon a level surface; Fig. 6 represents the apparatus working upon an incline.

Reference numeral 1 designates an angle secured bearings 2 in which are journaled the axles 3 of supporting wheels 4. One end of each of said axles 3 has aflixed thereto a worm gear 5. Said gears are inclosed in cases 6 and are engaged by worms 7, in the upper part of said case, said worms being on a shaft 8, on which are clutches 9 and 10.

Loosely mounted on shaft 8 are gears 11 and 12 in a case 13. A gear 14 on a cross shaft 15 meshes with gears 11 and 12. Cross shaft 15 has a worm gear 16, in case 17, driven by a worm 18 in the upper part of said case, said worm being connected by means of a flexible coupling 19 with the armature shaft of the motor 20, inclosed in housing 21, the front part of which 22, is removable to allow access to the. motor.

Clutches 9 and 10 have grooves 23, in which the forks 24 of shifter 25 (Fig. 3) rest. The upper end of shifter 25 is engaged by a link 26, Fig. 1, the slotted end of which embraces a pin 27 upon a rocking lever 28, mounted on a shaft 29. The upper end of said rocking lever is supplied with a handle 30. The 0 posite end of shaft 29 carries lever 31 and weight 32. The end of lever 31 has a stud 33, engaged by a lever 34, pivoted in a bearing on sills 1.

Angle bars 35 are supported vertically on sills 1, being braced by angles 36, on which are bearings 37, carrying a shaft 38, on which is pulley 39. At a point between angle 36 and the rear of the apparatus is an upright 40, supporting an angle 41, carrying a journal 42, which su ports the shaft 43 of an idler 44. Upon the sill 1 is a bearing 45, supporting a shaft 46 of an idler 47. The conveyer belt 48 travels over pulleys 39, 44 and 47, and is sup orted by troughing idlers 49 and bottom i lers, not shown. One end of shaft 43 carries a sprocket 50, connected by a sprocket chain with a sprocket 51 upon the end of a shaft 52, journaled in bearings supported by upright 35. Shaft 52 has a gear 53, which drives the pinion 54, upon the end of a shaft 55, said shaft being supported in bearings in theends of arms 56. Shaft 55 carries a brush 57. Adjacent to pulley 39 is a hopper 58, the lower member of which 59, has a ring formed upon its upper edge, which is held by cleats 60.

A centrifugal distributer 61 is supported immediately below member 59 on a turntable 62, and is driven by means of a gear 63, driven by a pinion 64 on the armature shaft fixed to the front ends of sills 1.

of a motor 65, inclosed in housing 66. The forward end of turn-table 62 has a clamp 67, engaging a semi-circular angle plate 68, af-

Troughing idlers 69 are provided to guide the conveyer 48 as it goes onto the ulley 39. Trolleys 70 and 71 are provided to receive current from the trolley wires 72 and have suitable electrical connections with-motors 20 and 65.

The ends of shafts 3, opposite to those carrying gears 5, have thereon spur gears 7 3, which mesh with a rack 74, laid parallel to the tracks 75 on which wheels 4 travel.

A stop 77 may be affixed to or near rails 75. A conveyer 76 may be provided to deliver material to conveyer 48, and a motor 78, at the head end of conveyer 48, may be provided to drive the same. The mode of operation of this invention is as follows: Material being deposited upon conveyer 76, is delivered thereby to conveyer 48 and carried up over pulley 39 and deposited in hopper 48 and deflected by the latter onto the distributer 61 and thrown in the desired direction thereby. The conveyer 48, after leaving pulley 39, passes over and behind pulleys 44 and 47 and thence toward the front of the machine and to the pulley 78, driven by motor 77, from whence it returns over the bottom idlers toward the conveyer 76. The motor 20, by means of the mechanism previously described, imparts motion to wheels 4, and the apparatus travels along the tracks 75 uniformly distributing material at the side thereof. When the lever 34 contacts with one of the stops 76, motion is imparted to shaft 29, whereby the lever 28, the link 26, shifter 25 and clutches 9 and 10 are operated. By this means the travel of the apparatus is reversed and it moves in the opposite direction until lever 34 contacts with the stop 77 at the opposite end of the tracks 75, whereupon the machine moves in the original direction. When it is desired to throw the material to the opposite side of the machine, the motor 65 may be reversed, and the lower member 59 of the hopper 58 also revolved. When it is desired to o erate the machine upon an incline, the racr 74 is laid at the side of the track; The conveyer belt which may be the one designated by the numeral 7 7 is assed over the pulleys 39 and 44 and under t e pulley 47, as shown in Fig. 6. The distributer 61 is turned to discharge the material toward the front of the apparatus. .As the material accumulates in front of the machine, a new length of track is laid, the j oining of the belt is opened and a new length inserted, motor 20 is started and the machine runs up the incline until the belt is again in tension. This operation may be repeated as often as may be desired.
